"That's terrorist talk. Seriously. "

I would agree with you if such actions were taken by people who hold themselves accountable to no one but themselves. How many referendums have been held by any terrorist group into which atrocity would be carried out next? Have we ever seen coverage of what terrorists are going to do in the media or any accountability or seeking of approval or justifying their actions. No need for it if you are only accountable to yourself and your own self imposed morality.
